DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of an integral concrete base block having a buried foundation plate according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, an integral concrete base block having a buried foundation plate according to the present invention is a concrete foundation block embedded in a ground for fixing a column 5 to an upper end, And a buried foundation plate 20 composed of a base plate 21 and a buried aggregate portion 25. [

Since the base PC block 10 is formed in a precast concrete shape that is formed in a block shape by using concrete, the base PC block 10 is constructed so as to achieve smooth construction in a construction site.

As shown in FIG. 1, the basic PC block 10 is formed in a block shape, and generally has a cross-sectional shape such as a square or a rectangle having the same sectional area in the upper and lower portions. Sectional shape of the lower portion 10 may be formed to have a trapezoidal cross-sectional shape having a structure in which the side surface is downwardly inclined downward.

The base PC block 10 is a structure for fixing and supporting the column 5 of various types of facilities (e.g., decks and fences). The base PC block 10 can be installed on the upper part, (The lower 2/3 area based on the total height).

The base PC block 10 may have a through hole 11 formed therein so as to extend vertically and vertically so that the base PC block 10 can be installed while accommodating a connection line or the like necessary for a facility.

The buried foundation plate 20 is made of a metal material, and performs a function of coupling the base PC block 10 of the concrete material and the pillars of the metal material to each other.

2 and 3, the flush-type base plate 20 includes a base plate 21 exposed on the upper portion of the base PC block 10, And a buried aggregate part (25) formed in the lower part of the base PC block (10).

The base plate 21 is in the form of a plate having a constant thickness and is positioned so as to be in face-to-face contact with the upper surface of the base PC block 10.

The base plate 21 is configured to support the support on a flat upper surface in a horizontal state.

The struts are welded to the base plate 21 to form an integrated structure.

It is possible to form an electric wire inflow hole (not shown) penetrating the base plate 21 vertically and vertically so that electric wires or connecting wires can enter the column 5. That is, when the through hole 11 is formed in the base PC block 10, the base plate 21 having the wire inlet holes corresponding to the through holes 11 of the base PC block 10 is applied .

4 (a), the base plate 21 may have a plurality of protrusions 22 on its lower surface. That is, the top surface of the base plate 21 has a flat plane to maintain a right angle with the column 5, while a plurality of protrusions are formed on the bottom surface of the base plate 21, It is possible to maintain the bonding strength with the base PC block 10 more strongly.

4 (b), the base plate 21 may be provided with a finishing projection 23 formed along the circumference of the lower surface and protruding downward.

In the above, the finishing projection 23 has a downwardly protruding lower end with a pointed cross-sectional shape.

As described above, when the finishing projection 23 is formed on the base plate 21, the durability of the product can be ensured while preventing the occurrence of a minute gap on the boundary line with the base PC block 10, It is possible to prevent the phenomenon of being caught and to maintain the appearance of the appearance.

The buried aggregate portion 25 is formed to protrude from the bottom of the base plate 21 and is embedded in the upper portion of the base PC block 10.

The buried aggregate portions 25 have a plurality of (two in FIG. 2) spaced apart from each other at a lower portion of the base plate 21.

As shown in FIGS. 2 and 3, the buried aggregate portion 25 includes an aggregate joining portion 25a fixedly installed on a lower surface of the base plate 21, And a continuous cut 25b and an extended cut 25c.

The aggregate joining portion 25a is configured to face-join with the base plate 21, and is extended in the left-right direction.

Since the extension length of the aggregate joining portion 25a is formed to have a sufficient joining area of 1/3 or more in length based on the length of the base plate 21, It is possible to improve.

The vertical base cut 25b is formed to extend to a predetermined depth in the base PC block 10 and is bent and extended in the lower vertical direction at both ends of the aggregate joining portion 25a. And the base PC block 10 are sufficiently integrated with each other.

The extended cuts 25c are formed in parallel with the aggregate joining portions 25a at the lower ends of the vertical cuts 25b and are bent to extend in the transverse direction. In other words, the extended bone cutting 25c is extended in the lateral direction toward the inner side or the outer side at a position extending in the inner depth direction of the base PC block 10 along the vertical bone cutting 25b, It is possible to exert the binding force toward the horizontal direction with respect to the base 10 and to further improve the coupling efficiency.

Although the extended rib cutting 25c is configured to extend toward the outer horizontal direction with reference to the position of the vertical rib cutting 25b, the present invention is not limited thereto, The cutter 25 may be configured to extend in the inner horizontal direction with respect to the vertical cutter 25b, and the cutter 25c may extend in the inner horizontal direction with respect to the vertical cutter 25b It is also possible to integrally form the vertical frame cuts 25b arranged at left and right intervals so as to connect them together.

A curve-shaped curved connecting end 25d is formed between the vertical curved cut 25b and the extended curved cut 25c. Since the curved connecting end 25d is formed in a curved shape at a connecting portion bent from the vertical curved cut 25b to the extended curved cut 25c, The force from the load in the vertical or horizontal direction equally acts on the entirety of the curved connecting end 25d to prevent shearing due to a local force, and at the same time, durability of a good product can be achieved.
